我开始使用弹性搜索。我成功在我的服务器上安装了弹性搜索（与应用程序服务器不同）。但是当我尝试从我的应用程序服务器调用弹性搜索时，它给出了错误
Fatal error: Uncaught exception 'Elasticsearch\Common\Exceptions\NoNodesAvailableException' with message 'No alive nodes found in your cluster'当我检查 Elastic search 状态时，它显示 Active。
如何将 Elasticsearch 从我的应用程序服务器调用到我的 Elasticsearch 服务器。
<?php
require 'vendor/autoload.php';
$hosts = [
'ip_address:9200' // IP + Port
];
$client = Elasticsearch\ClientBuilder::create()->setHosts($hosts)->build();
$params = [
'index' => 'my_index',
'type' => 'my_type',
'id' => 'my_id',
'body' => ['testField' => 'abc']
];
$response = $client->index($params);
?>
我的elasticsearch.yml设置
# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
# Before you set out to tweak and tune the configuration, make sure you
# understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please see the documentation for further information on configuration options:
# <http://www.elastic.co/guide/en/elasticsearch/reference/current/setup-configuration.html>
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: node-1
#
# Add custom attributes to the node:
#
# node.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
# path.data: /path/to/data
#
# Path to log files:
#
# path.logs: /path/to/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
# bootstrap.memory_lock: true
#
# Make sure that the `ES_HEAP_SIZE` environment variable is set to about half the memory
# available on the system and that the owner of the process is allowed to use this limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
#network.host: 0.0.0.0
#network.bind_host: 0
#
# Set a custom port for HTTP:
#
# http.port: 9200
#
# For more information, see the documentation at:
# <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html>
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when new node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
# discovery.zen.ping.unicast.hosts: ["host1", "host2"]
#
# Prevent the "split brain" by configuring the majority of nodes (total number of nodes / 2 + 1):
#
# discovery.zen.minimum_master_nodes: 3
#
# For more information, see the documentation at:
# <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery.html>
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
# gateway.recover_after_nodes: 3
#
# For more information, see the documentation at:
# <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-gateway.html>
#
# ---------------------------------- Various -----------------------------------
#
# Disable starting multiple nodes on a single system:
#
# node.max_local_storage_nodes: 1
#
# Require explicit names when deleting indices:
#
# action.destructive_requires_name: true
elasticsearch.yml 设置不起作用
network.host: 127.0.0.1network.host: 0network.host: 0.0.0.0network.host: IP_Addressnetwork.bind_host: 0network.bind_host: IP_Address当我设置上述设置后，elasticsearch 显示失败状态。
注意：Elastic search 安装在与我的应用程序服务器不同的服务器上。
我发现了错误。错误是由于 node.name 和 cluster.name 之前的空格而出现的。删除空格并且工作正常。
更新了elasticsearch.yml文件

PHP 代码

require 'vendor/autoload.php';
$indexParams = [
'index' => 'my_index',
'body' => [
'settings' => [
'number_of_shards' => 5,
'number_of_replicas' => 1

成功响应：
Array

我发现了这个错误并通过以下步骤解决了它：
注释 app/etc/env.php 文件中的插件设置。
'system' => [
'default' => [
/* 'smile_elasticsuite_core_base_settings' => [
'es_client' => [
'servers' => 'node-1:9200,node-2:9200',
'enable_https_mode' => '0',
'enable_http_auth' => '0',
'http_auth_user' => '',
'http_auth_pwd' => ''
]
] */
]
]
启动服务器。
升级magento
php bin/magento setup:upgrade
我也面临着同样的问题。我在主机“myhostaddress:9200”中指定。将其更改为 Elasticsearch 主机服务器的 IP，例如 '127.0.0.1:9200' 。它解决了我的问题。
如您所知，多年后，S.O 也被用作社区基于关键字的参考。因此，我要加入一个关于解决此
No alive nodes found in your clusterElasticsearch PHP Client > Connecting documentation section$client = ClientBuilder::create()
->setElasticCloudId('<cloud-id>')
->setBasicAuthentication('<username>', '<password>')
->build();
那么您应该尝试添加 CA Bundle 验证：
$caBundle = \Composer\CaBundle\CaBundle::getBundledCaBundlePath();
$client = ClientBuilder::create()
->setElasticCloudId($ES_CloudID)
->setSSLVerification($caBundle)
->setBasicAuthentication($ES_username, $ES_password)
->build();
我证明注释掉
->setSSLVerification($caBundle)您的答案可以在我提供的链接中找到https://forums.aws.amazon.com/thread.jspa?threadID=230626 我遇到了同样的问题，但通过此链接它解决了，建议在最后附加后缀 :443 的答案将起作用
删除弹性搜索中的尾部斜杠。有时它会产生错误。
至少在我的例子中，我从 Amazon ES URL 中删除了尾部斜杠使其正常工作。
Elasticsearch-PHP 和 Elasticsearch 之间的版本不匹配可能会发生这种情况。 Elasticsearch-php 库 github 页面中记录了它们之间的兼容性：https://github.com/elastic/elasticsearch-php?tab=readme-ov-file#compatibility
Elasticsearch 客户端与当前维护的 PHP 版本兼容。
语言客户端向前兼容；意味着客户支持 与更高或同等次要版本的 Elasticsearch 进行通信，无需 打破。并不意味着客户端自动支持新功能 较新的 Elasticsearch 版本；只有在发布新版本后才有可能 客户端版本。例如，8.12客户端版本不会自动支持 Elasticsearch 8.13版本的新特性，8.13客户端版本 为此需要。 Elasticsearch 语言客户端只是倒退 与默认发行版兼容且不做任何保证。
| Elasticsearch 版本 | Elasticsearch-PHP 分支 | 支持 |
|---|---|---|
| 主要 | 主要 | |
| 8.x | 8.x | 8.x |
| 7.x | 7.x | 7.17 |
